DS2431+ Frequently Asked Questions (FAQs)

  • Up to 256 devices can be connected to a single 1-Wire bus, but it's recommended to limit it to 100 devices for reliable operation.
  • Use a 1-Wire bus repeater, such as the DS2482-100, to amplify the signal and improve reliability over long cables.
  • No, the DS2431+ is designed to operate from 2.7V to 3.7V, and using a 5V power supply may damage the device.
  • Use a 1-Wire bus reset circuit, such as a 1kΩ resistor and a 100nF capacitor, to ensure a clean reset signal to the DS2431+.
  • The DS2431+ EEPROM has a minimum data retention period of 10 years, but it can be extended up to 40 years or more depending on the storage conditions.
